IEA  |  Hydrogen patents  for a clean energy future
Competition to be the leader in hydrogen innovation is intensifying and has the potential to drive commercialisation. The stakes are high: installations of electrolysers reach 380 gigawatts in 2030 in the International Energy Agency’s (IEA) Net Zero Emissions by 2050 Scenario, illustrating the economic opportunity for countries that can translate research excellence into industrial competitiveness.
However, activity remains concentrated in a small number of regions, limiting the exchange of ideas. Looking ahead, hydrogen innovation must address specific national challenges, for example by helping Africa tap into some of the lowest-cost clean energy on the planet. This study, which showcases the growing partnership between the IEA and the European Patent Office (EPO) after our work on batteries (2020) and low-carbon energy (2021), is the most comprehensive comparison of patenting trends across the full hydrogen value chain. Such an integrated approach is essential for hydrogen, which relies on multiple technologies to connect supply and demand.
